Catalysts for Synthesis of Biodiesel: A Review

Because of the increasing demand for energy in the world, on the one hand, and limited sources and environmental subjects about fosile fules one the other hand in recent years, many studies have been conducted in different countries in order to provide a good source of alternative fuel. Among the different fuels‬, ‬biological fuels (biodiesel and bioethanol), one of the most desirable alternative materials have been introduced. Biodiesel as a green fuel (Mono Alkyl ester) is a clean fuel that is produced from renewable natural resources such as oil seeds, plant oils, algae and food waste. Type and conditions of selection process for biodiesel production, is a function of feed intake, production capacity and position in a manufacturing process, and so on. Catalysts play an important role in the biodiesel production process. In recent years, the increasing demand for biodiesel, the goal is to find ways to make the economics of biodiesel production, increased efficiency of the production process as possible, and at the same time, the properties of biodiesel produced in accordance with standards available. The best and most practical research, is the catalyst of process. This paper examines the role of catalysts used in biodiesel production and research in this field has been investigated.
